13 ABSTRACT OF THE DISCLOSURE When depositing layers of lumber (19) onto a support surface to form a stack (17) of lumber, spacing sticks (2) are placed between the various layers at right angles to their longitudinal direction. One or more laying means (20), which carry the layers of lumber, move either continuously or intermittently towards, over and away from said stack support surface (21) on which the layers of lumber are placed The spacing sticks (2,2') are inserted between separate layers of lumber by means of a movable means (13) which, while engaging one end of respective sticks, feeds said sticks substantially parallel with the direction of return movement of the laying means (20). The problem of laying the layers of lumber and the spacing sticks in a manner such that they interfere with one another to the least possible extent is hereby solved in a simple and reliable manner. Pre- ferably the engaging means feeds the spacing sticks separately from an overlaying magazine (1) and maintains engagement with respective spacing sticks until said means has reached a remote turn position, at which the spacing stick is deposited onto the stack support surface or onto a partly formed stack, or to a preferably pivotable spacing-stick guide means (18) ar- ranged on the opposite side of the stack support surface. The invention also relates to a spacing stick laying means arranged adjacent a stack support surface (21) for receiving layers of lumber (19) . The said spacing stick laying means is arranged to operate in the aforedescribed manner. To this end, the spacing stick laying means comprises means in the form of a clamping arm (13) having a spring-loaded jaw means (14) which,while en- gaging one end of a spacing stick (2) supports said stick in a free-bearing manner during said feed movement.
